When I am in 4th, if I release the accelerator, the "engine brake" seems to make the car "flutter" (or shake)....this only happens in fourth...any ideas??

 

Come on guys....someone has to have an idea!!

 

how fast and at what rpm are you ? if it's 2 low and in ss, i would assume you go into a stall...

 

No.....assume you are sruising in town on a high speed street (45-55 mph)....you get to speed in 4th gear, and then let off of the gas to slow yourself a bit. It feels like it would if the brakes were warped.....but they aren't. and it's only in fourth...not any other gear does this.....

I'm fucking stumped...
